The SprintIR carbon dioxide sensor is the fastest, most accurate CO2 sensor on the market. A breakthrough in NDIR technology, the SprintIR uses advanced solid state Indium Antimonide LED’s and detectors to offer a robust sensor with no moving parts, no heated filaments, and incredibly low power requirements. The sensor comes in four versions - from 5%, to 100% - all capable of the same high-speed CO2 measurement. This makes the SprintIR especially useful in biological applications.
